Not sure what to think......

[Confused02]

Ok first of all I am 21, well i went on like 5 or 6 dates with a 18 year old girl i didnt think it was going that bad she was texting me everyday and whatnot so i thought she was pretty interested. Well the last time she was with me we were at my house and it started with kissing and we almost had sex. I stopped myself because i wasnt sure if she was ready, before i started I told her "all you have to do is stop me if your uncomfortable" well i really dont think she was going to . Well i was getting the vibe to stop anyways i didnt want to rush things thats pretty much what i told her. Well three days past by and she didnt text me but when i texted her she would text right back. So finally today i asked her what was goin on in a polite way i asked her if it had anything to do with that night and she said no. She said i was a nice guy but the age difference was a big thing. Well i ended up calling her and asked her if she wanted to give it another shot. We went out again and it didnt go that great she blew me off twice after that this go around I was just tryin to sleep with her because i thought that was what she wanted. i invited her over to watch movies and she didnt want to she said she didnt feel like movies. I finially asked her if she was looking for anything serious and she said no. I told her I was cool with that all she had to do was tell me she sent me mixed messages. Well it went on and on i told her i wasnt looking for serious and asked if she wanted to hang out. She said we could hang out as friends so i thought she was leaning towards **** buddy so I asked her if she was physically attracted to me and she said no that kinda shut me down. idk what to think i asked her why she went back out with me and she said "it was sort of a final date thing i guess, i thought we were going to talk about why we broke up". Well at this point i kinda gave up i was like "just tell me somethin and be honest were you looking for fun or someone to date" she said someone to date. Should i let this be or straight ask her is she wants to hookup?
